Newag 222M (SA140 series) is a two-cardiesel multiple unit produced by theNewag company fromNowy Sącz. Two units were manufactured forMasovian Railways, and four more for theSubcarpathian Voivodeship.
In September 2009, thePomeranian Voivodeship announced a tender for two- and three-cardiesel multiple units (DMUs).[7]Newag, aiming to enter a new market, collaborated withKraków-basedEC Engineering [pl] to design these vehicles (models220M and 221M) and began production in February 2010, even before signing a contract with the Pomeranian Voivodeship on 21 May 2010.[7] Newag went on to sell more DMUs from the 220M/221M family, including one to theLubusz[8] andSilesian voivodeships.[9] The 222M model, which meets TSI standards and includes the "four collision scenario", is an advanced development of these earlier models,[10] also designed by EC Engineering.[1]
Before signing its first contract for the 222M DMU, Newag won two tenders offering this model but failed to finalize contracts. In May 2012, Newag submitted the winning bid for two DMUs for theWest Pomeranian Voivodeship but backed out of signing the contract.[11] Consequently, on 2 July 2012, the voivodeship signed the deal withPesa.[12] A similar situation occurred in the Lubusz Voivodeship, where Newag won a tender for four units in January 2013[13] but again refrained from signing, leading the voivodeship to sign with Pesa on 15 March 2013.[14]

The first 222M unit was successfully contracted by the Masovian Railways on 18 June 2013.[15] In October 2013, the vehicle underwent testing inKraków,Grybów, andOlsztyn.[16] Later that month, it was tested at theTest Track Centre near Żmigród, remaining there until October 29.[17] On November 20, the vehicle received certification for operation on thePKP Polskie Linie Kolejowe network.[4]
On 16 June 2015, Newag signed a contract with Masovian Railways for another 222M unit. In early 2017 and mid-2019, Newag signed contracts for the delivery of two 222Ma DMUs for theSubcarpathian Voivodeship.[18][19]

Access to the 222M interior is provided through a pair of sliding doors on the side of the vehicle, each 1,300 mm wide with a step 600 mm above the rail head.[3]
The vehicle is adapted for transporting passengers with mobility impairments. It includes a platform at one set of doors to facilitate boarding, a dedicated area for a wheelchair, and a TSI PRM-compliant accessible toilet.[3]
Additionally, the unit is equipped with forced-air heating, dual-zone air conditioning, 230 V power sockets, a passenger information system, and surveillance cameras.[3]

The two-car unit is based on three two-axlebogies: two end drive bogies (type 74RSNa)[21] and a shared middle, non-powered bogie in theJacobs system (type 72RSTa),[21] which supports both cars.[3]
The propulsion system includes two drive units with a 390 kW diesel engine, an automatic hydrodynamic transmission with aretarder. The engines meetStage IIIB emissions standards.[3]
The 222M body meets the following standards: structural strength (PII according to EN 12663), fire resistance (PN-K 02511), and crashworthiness (EN 15227) for four collision scenarios.[3]
